Title: Image processing device
Inventor: IKEDA KAZUTAKA
IPC: G01B11/24
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide an image processing device capable of accurately setting a go/no go criteria. SOLUTION: A checking section 13 classifies inspected objects into defects, non-defects when reliability is equal to or more than prescribed among non- defectives, and undecided non-defects when reliability is less than prescribed among non-defects, on the basis of images of the inspection objects picked up by a TV camera 2. An image memory section 12 stores a plurality of images of at least detects and undecided non-detects. Since the image memory section 12 stores images of both cases that the non-defects are misjudged as defects and vice versa, by adjusting a go/no go criteria based on the images stored in the image memory section 12, it is possible to set the go/no go criteria more accurately than conventional.

Title: Semiconductor device
Inventor: HARA TOSHITAMI
IPC: H01S5/00
Filed: 1986-05-19
Abstract: PURPOSE:To obtain a state of favorable image-formation when preferable arrangements of semiconductor emitter are incorporated into an optical device by forming a light emission end face of each semiconductor emitter at a limited angle and arranging light emission points to be emitted from the above end face on an identical line. CONSTITUTION:After preparing semiconductor emission elements such as its element like double hetero-structures on a substrate of GaAs 11, a photo mask forms a fanwise pattern where respective light emission end faces are formed so that they are shifted by the angles of theta1 and theta2 each other. Since the end faces facing each other and forming Fabry Perot resonance faces are also slidden by the angles theta1 and theta2, such a state permits resonance directions to be shifted by the angles theta1 and theta2 and also light emission directions 12a-12e to be different accordingly. In such a case, the resonance faces are formed as if lights ware emitted from a point Po or its vicinity that is located at the opposite side of light emission side. As a result, the resonance faces cause emission points 100a-104a to be arranged nearly on one straight BB' line. This approach helps in correcting the defocusing of the imageformation.

Title: Dc offset elimination circuit for digital signal
Inventor: SATO YASUAKI
IPC: H03M1/12
Filed: 1989-05-09
Abstract: PURPOSE:To eliminate only a DC offset component by extracting a DC offset component of an input signal with a low pass filter so as to subtract the component from an input digital signal. CONSTITUTION:An output of a 1st-order cyclic digital filter (low pass filter) 1 represents a DC offset quantity of an input digital signal. The output of the low pass filter 1 is latched based on a latch signal supplied from a latch signal generating section 7 in a proper timing and fed to a subtraction circuit 8. The latched value from the input digital signal is subtracted at the subtraction circuit 8 to obtain a signal from which the DC offset component is eliminated. Thus, an output from which almost a pure DC component only is eliminated is obtained without losing an ultralow component of the input signal.

Title: Optical relay system
Inventor: ASAKO KATSUHIRO
IPC: H04B10/03
Filed: 1992-05-07
Abstract: PURPOSE:To reflect an optical signal on the occurrence of a line fault in a repeater employing an optical direct amplifier amplifying directly the optical signal without conversion of the optical signal into an electric signal CONSTITUTION:When a discontinuity fault takes place between stations A and B in an incoming line, since an optical signal is interrupted at the station B, an input interruption detection circuit 13 detects an input interruption and its control signal is used to open an optical shutter 14W, then an optical signal travels to an incoming photocoupler 2E. An optical signal for an outgoing line is reflected in the photocoupler 2E and sent to the incoming line. Furthermore, the input interruption signal is used to control a stimulation semiconductor laser 10W of the station B so as to prevent current flowing and the optical signal being an output of a photocoupler 2W is attenuated by a wavelength split multiplexer 6W and cannot reach the outgoing (W) of the station A. Similarly, an input interruption detection circuit 13W of the station A is operated and the optical signal inputted to an incoming line (E) of the station A is reflected and sent to an outgoing line of the station A.

Title: Method and device for detecting light acoustic signal
Inventor: NAKADA TOSHIHIKO
IPC: G01N21/00
Filed: 1991-05-20
Abstract: PURPOSE:To enable a surface of a sample and an internal information to be detected in a simple configuration and stably by eliminating a need for adjusting a relative light axis between an excitation light for generating a light acoustic effect and a probe light for detecting the light acoustic effect. CONSTITUTION:A reflection light 61 and a reference light 59 from a sample are subjected to heterodyne interference and a frequency component which is two times larger than a modulation frequency of the excitation light from the interference light is detected 300, thus enabling generation and the detection of light acoustic effect to be performed with one beam light. Since generation and detection of the light acoustic effect can be performed with one beam light, relative adjustment of light axis between the excitation light and probe light is not needed and a stable and highly sensitive detection can be made. Also, a resolution in side direction can be improved by adopting a common focusing optical system.

Title: Ferromagnetic thin film and manufacture thereof
Inventor: NAKATANI RYOICHI
IPC: H01F41/18
Filed: 1987-05-13
Abstract: PURPOSE:To achieve a ferromagnetic thin film having a low coercive force and high permeability by providing the angle made by the direction of incidence of an ion beam and the direction of the substrate center as viewed from the target center which is equal to or greater than 80 deg. and smaller than 180 deg.. CONSTITUTION:Substrates 14 are concentrically placed around a target 12 using a substrate holder 15. The angle 16 of the target 12 from the horizontal line is to be 45 deg.. An Ar ion beam generated in an ion gun 17 flies in the direction of an arrow 18, impinging on the target 12. As a consequence, the target 12 is sputtered, whereby a permalloy thin film is formed on a substrate 14. If the angle made by the direction of incidence 18 of the ion beam and the direction 19 of the substrate center as viewed from the center of the target 12 is 20, the film thickness, coercive force and relative permeability of the permalloy thin film vary depending on the value of the angle 20. If the angle is 80 deg. or greater, a coercive force not greater than 30e and a relative permeability not smaller than 500 are obtained. Also, if the angle 20 is 180 deg. or greater, the suppertering particles do not reach the substrate, so the angle 20 needs to be smaller than 180 deg..
